这是一个很好的matlab的学习资料，希望对你们有帮助，提供了很多matlab基本函数(This is a very good learning matlab data you want to help provide many basic functions matlab)

用以计算迭代动力系统的Lyapunov指数.当此指数小于0时,系统是稳定的.(Iterative dynamic system for the purpose of calculating the Lyapunov index. When the index is less than 0:00, the system is stable.)

异步电机仿真，查看电机性能的matlab仿真程序，希望对大家有所帮助(Induction motor simulation, see the electrical properties of matlab simulation program, I hope all of you to help)

这个个程序是利用卡尔曼滤波实现人体关节点的跟踪问题，运用的是CV模型，噪声为高斯白噪声！有用的拿去看看！(This procedure is to use a Kalman filter to achieve a key point in human tracking problems, the use of the CV model, noise is Gaussian white noise! Take useful to see!)

为带通滤波器，需设置半阶数、高低截止频率和采样频率。保存为function函数的m文件。rar中为一肌电信号。(For band-pass filter, to be set up semi-order, high and low cutoff frequency and sampling frequency. Save it as a function of m file function. rar for a EMG.)

用于语音端点检测，可以将连续语音分割为孤立词。(For voice activity detection, continuous speech can be split into isolated words.)

this file content simple example about modulation bit stream.the type of modulation is (FSK,PSK and ask) after modulation data send and received after that show the relationship between signal to noise ratio (snr) and the bit error rate (ber).....

载机使用雷达和红外装置对目标进行跟踪定位，对它们的测量值使用数据融合技术进行处理，使得跟踪结果更精确。(Carrier aircraft using radar and infrared devices on the target for tracking and positioning of their measurements using data fusion technology for processing, so that the tracking results more accurate.)

方便初学者学习使用matlab软件，使用方法介绍的比较详尽(Convenience of beginners learning to use matlab software, use of a more detailed introduction)

空间谱估计music 谱估计方法,估计信号参数(Spatial spectrum estimation music spectrum estimation methods, estimates signal parameters)
